SPECIFICATION forming part of Letters Patent No. 727,834, dated May 12, 1903.

Application filed December 19,1900. Renewed September 25, 1902. Serial No. 124,871. (No model.) 7

To all whom, it may concern.-

Be it known that I, WALTER N. PHILLI- Press; and I do hereby declare the following. to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

My invention has for its object to provide a com bined pad-moistener and copying-press, the construction being such that the copying- ,pads will be kept at all times properly moistened and ready for use on the lower platen of the press, while said press may at the same time be used for copying purposes.

A further feature of my invention is that the pressure exerted on the pads when in position for being moistened is that exerted by the platens of the copying-press, which may be controlled at will.

Stillanother feature of myinven tion is that the same may be added to ordinary presses now in use without necessitating any change in the mechanism thereof.

In the accompanying drawings, Figure 1 is a vertical section of a letter-copying press, showing my'device in position therein, also in section, the section being taken transversely of the water-reservoirs. Fig. 2 is a section showing same adapted to a hydraulically-operated letter-copying press. Fig. 3 is a section on a plane at a right angle to the section shown in Fig. 2.

In the figures like reference characters are employed as far as possible in the designation of corresponding elements of construction in all the views.

A is the press, which may be of any desired form, comprising, however, a dead-platen 0., posts a, a cross-head or abutment a and means for producing power and applying it to a movable platen a such means being typified in the drawings by a screw a, as in Fig. 1, and a hydraulically-operable piston and cooperative elements, as shown in Figs.

2 and 3. However, the only requisite of this device is that there be provided such means as will cause a compressing force between two flat surfaces sufficient to express the water both in copying letters and tempering the moisture of the pads.

' The moistener as shown in Fig. 1 will first bedescribed and then the slight modification such a nature as to be not easily corroded by water.

This plate B should be substantially coextensive with the face of the said platen, and either has its ends turned downwardly and formed into a trough b, with ends secured thereto, or has a trough attached or in close juxtaposition thereto and in which is formed a small opening for the entrance of water and through which the ends of the wick C may be introduced, said wick being of a thick fabric suitable to raise the required amount of water by capillary attraction and feed it to the pile of pad D, superposed thereon, either with'or'without the interposition'of a perforated plate E,which is of thin metal, also practically non-corrodible and perforated in such proportion to its area as will best serve the purpose of controlling the amountof water fed to the pads, and by reducing the surfacewhich feeds to the pads in proportion to the capillary capacity of the wick cause a thorough distribution of the water to the said pads throughout their entire surfaces. A thin metal plate F, ,guided, if desired, in its movements by suitable engagement with the posts (2, serves to seal the upper side of the aggregated pads to prevent evaporation therefrom and also prevents communication of the water therein to the movable platen or the book-cover contiguous and prevents the pads from being displaced by contact with the book when inserted and removed.- The edges of such parts, if desired, should be rolled, wired, or flanged to confine the drainage, &c.

In Figs. 2 and 3 thewater-reservoirs are made integral with the lower platen of the press, which for convenience of operation hydraulically is the movable platen, the reverse of the ordinary screw-actuated -lettercopying press. In this showing of the device the perforated plate E is also omitted and the Water-reservoir extends along all four edges of the movable platen. These alterations are rendered possible with efficiency in view considering that these hydraulieallyoperated presses would only be used where a very large amount of copying was to be done and a commensurately large number of pads require moistening, rendering the natural distribution of the Water through the mass of pads more equal and the requirements as to quantity of water stored greater.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-- 1. A combined pad-moistener and copyingpress, consisting of a stationary and a movable platen, means for operating said movable platen, a trough in operative relation to the lower one of said platens and adapted to contain water, and a wick lying across said platen and communicating with said trough.

2. A combined pad-moistener and copyingpress, consisting of a stationary and a movable platen, means for operating said movable platen, a trough in operative relation to the lower one of said platens and adapted to contain water, a wick lying across said platen and communicating with said trough, and a plate lying between the upper platen and the pads to be moistened and adapted to receive the matter to be copied.

3. A combined pad-moistener and copyingpress, consisting of a stationary and a movable platen, means for operating said movable platen, a removable plate lying across the lower one of said platens and extended into or carrying at one or more of its edges a trough or troughs for containing water, and a wick lying across said plate and com municating with said trough or troughs.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
